Broadcom chips target infotainment
October 1, 2013 by John Day
Broadcom’s wireless automotive portfolio consists of the BCM89335 5G WiFi/ Bluetooth Smart Ready combo chip and the BCM89071 Bluetooth + Bluetooth Smart Ready chip. Both are now sampling.
Broadcom said the chips will allow drivers and passengers to easily sync and stream content from mobile devices to the car’s infotainment system and rear-seat displays.
The chips will also enable high-speed connectivity beyond the vehicle, serving Internet and cloud content via LTE telematics or directly from a Hot Spot connection.
Based on the latest generation IEEE 802.11ac standard, the integrated 5G WiFi technology provides the bandwidth required for multiple in-car displays and resolution of up to 1080p, allowing uncongested 5GHz video to coexist concurrently with 2.4GHz Bluetooth hands-free operation.
Bluetooth Smart Ready technology, which allows products to sip power at an incremental rate, will play a vital role in enabling connectivity between the car and wearable tech and body sensors, such as the ability to monitor biometric indicators including driver fatigue, blood alcohol content and glucose levels.
“Car connectivity is the new battleground for product differentiation and the next frontier for Broadcom,” said Rahul Patel, Broadcom Vice President of Wireless Connectivity.
Analysts predict the use of in-car Wi-Fi-enabled applications to grow eightfold by 2019 as car makers leverage the latest technologies to differentiate in an increasingly competitive market. One of the most immediate applications enabled by Wi-Fi and Bluetooth Smart is the smart remote, allowing drivers to use their smartphone to remotely adjust seat, temperature and infotainment settings while providing vital data on automotive performance and diagnostics.
Bluetooth Smart technology can seamlessly sync mobile devices to the vehicle audio and display system, and the technology also offers great promise for new innovations in vehicle to person, vehicle to vehicle and vehicle to infrastructure communications (V2X).
Designed to improve both driver and traffic safety, V2X communications will allow drivers to anticipate upcoming road hazards, traffic incidents and monitor speed limits. For example, when the V2X system reports a blocked road or traffic jam on the route, future vehicles will have the ability to automatically adjust speed or calculate an alternative route. Infrastructure development and smart highway initiatives are already underway throughout Europe and the United States.
